Harald Welte e6afd60779 [gprs] SGSN: Expect all Identifiers to be stored at highest level 
We now expect the highest level (actual SGSN GMM code) to know
all identifiers for every element in the protocol stack, i.e.
TLLI, SAPI, BVCI and NSEI.  The layer-inetrnal state is looked
up based on those identifiers.

The reason for this is to ensure only the highest level state
needs to be persistent, while everything else can be regenerated
dynamically (e.g. in a SGSN restart)

About OpenBSC
=============

OpenBSC is a minimalistic implementation of the GSM Network, with
particular emphasis on the functionality typically provided by the BSC,
MSC, HLR, VLR and SMSC.

Its currently supported interfaces towards the BTS are:

 * Classic A-bis over E1 using a mISDN based E1 interface. In other
   words, you can connect existing GSM Base Transceiver Station (BTS)
   through E1 to OpenBSC.  So far, we have only tested the Siemens BS-11
   Test reports with other BTS are much appreciated!

 * A-bis over IP as used by the ip.access nanoBTS product family

This project is still in its early days, and there are lots of areas where it
doesn't behave as per GSM spec.

libosmocore
===========

Please note that as of March 2010, OpenBSC has a dependency to a library
called "libosmocore".  You can obtain that library from

	git://git.osmocom.org/libosmocore.git
